A
RegisteredContentScript
is returned by a call to
contentScripts.register()
and represents the content scripts registered in that call.
It defines a single function
unregister()
, which can be used to unregister the content scripts.
注意： If this object is destroyed (for example because it goes out of scope) then the content scripts will be unregistered automatically, so you should keep a reference to this object for as long as you want the content scripts to stay registered.
unregister()
Unregisters the content scripts represented by this object.
BCD tables only load in the browser
This code toggles a registered content script on a browser action click:
var registered = null;
async function register() {
registered = await browser.contentScripts.register({
matches: ["*://*.org/*"],
js: [{
code: "document.body.innerHTML = '<h1>This page has been eaten<h1>'"
}],
runAt: "document_idle"
});
}
function toggle() {
if (registered) {
registered.unregister();
registered = null;
} else {
register();
}
}
browser.browserAction.onClicked.addListener(toggle);
